python - ImportError:没有名为bb的模块

要创建一个helloworld .ipk包，如here所述，我将bitbake和OpenEmbedded克隆为

git clone git://git.openembedded.org/bitbake
git clone git://git.openembedded.org/openembedded


然后导出以下变量

export OEBASE=/media/sda3/open_env/
export PATH=$OEBASE/bitbak/ebin:$PATH
export BBPATH=$OEBASE/build:$OEBASE/openembedded
export BB_ENV_EXTRAWHITE="OEBASE"


当我运行以下命令时，出现以下错误：

bitbake -b packages/myhelloworld/myhelloworld_0.1.bb

Traceback (most recent call last):
  File "/usr/bin/bitbake", line 35, in <module>
    import bb
ImportError: No module named bb


我正在ubuntu 10.04上执行此操作。我在这里想念的是什么？

编辑：

如答案中给出的，我执行了以下命令并得到如下错误：

git clone git://git.openembedded.org/openembedded-core
cd openembedded-core
git clone git://git.openembedded.org/bitbake

cd ..
git checkout dylan
cd bitbake
git checkout 1.18
cd ..

. oe-init-build-env


修改build/conf/local.conf并在myhelloworld目录中创建openembedded-core/build/目录，然后执行

bitbake myhelloworld/


我收到以下错误消息：

最佳答案

您正在将最近的Bitbake与OpenEmbedded classic混合使用；请不要那样做。您还尝试手动设置构建环境，也不要设置该环境。任何新开发都应基于OpenEmbedded Core。

您应该做什么：


克隆存储库。

git clone git://git.openembedded.org/openembedded-core
cd openembedded-core
git clone git://git.openembedded.org/bitbake


如果要使用某个分支，例如jethro

git checkout jethro
cd bitbake
git checkout 1.28
cd ..


请参见corresponding release branches of OE-core and bitbake。
设置构建环境：

. oe-init-build-env

配置构建。

即在build/conf/local.conf中设置正确的机器等。
建立！

现在您想要什么，例如任何：

bitbake core-image-minimal
bitbake myehelloworld



更新：请注意，最后一个发行版（Poky，已针对Ubuntu 10.04进行了正式测试，是Dylan）。以后的发行版很可能在该主机上存在问题，我建议更新到较新的LTS发行版。

更新2：您的新错误为ImportError: No module named pysqlite2。 Bitbake首先会查找sqlite3。将其安装在您的构建主机apt-get install libsqlite3-dev上
